Comment (by Đonny):

 Replying to [comment:6 cehoyos]:
 Sorry, I originally didn't understand what was your command good for. Now
 I got it.
 I can reproduce the error by running
 {{{
 ffmpeg -f lavfi -i testsrc -t 10 -f mjpeg d:\temp\xxxyyy.avi
 }}}
 and then running
 {{{
 ffplay d:\Temp\xxxyyy.avi
 }}}
 or
 {{{
 ffprobe d:\Temp\xxxyyy.avi
 }}}

 both give me error, though a little bit different then on my file
 {{{

 If I rename xxxyyy.avi to xxxyyy.mjpeg both - ffprobe and ffplay work
